ABSTRACT:
A light-tight enclosure for storing and dispensing a roll of photosensitive web material wound about a hollow cylindrical core having open opposite ends. The enclosure comprises a flexible opaque bag with opposite sidewalls extending between opposing rearward and forward portions and opposing upper and lower portions. Each sidewall has a central aperture therein congruent with each core end. The rearward portion defines a closable opening for receiving the roll. A shallow neck portion projects from the forward portion to an end thereof defining an exit slot for dispensing the web material. A collar fits tightly inside each core end, with an annular flange thereon facing axially outward. An annular ring is attachable to each collar in spaced, inward-facing relation to the flange. The roll is first positioned in the bag, through its closable opening, so that the web material extends into the neck portion and out through the exit slot, and so that a central portion of the collar at each core end projects outwardly through the adjacent sidewall aperture, with its flange left inside the sidewall and facing an annular portion thereof surrounding the aperture. The annular ring is then attached to the outwardly projecting portion of the collar in closely spaced, inward-facing relation to the sidewall annular portion, which is thus loosely trapped between the flange and the ring. The bag opening is then closed, and the bag neck portion is folded back and secured against the bag forward portion.
